Alloy 601 Round Bar Nickel Alloy Bar UNS N06601 Inconel 601 Round
Bar Alloy 601 Round Bar is a high-performance nickel-chromium alloy renowned for its
exceptional oxidation resistance, high-temperature strength, and
excellent mechanical properties. Below is a detailed description of
its composition, characteristics, and applications:
CompositionAlloy 601 is primarily composed of: Nickel (Ni): 58-63% – Provides excellent corrosion resistance and
high-temperature strength. Chromium (Cr): 21-25% – Enhances oxidation and corrosion resistance. Iron (Fe): Balance – Forms the base of the alloy. Aluminum (Al): 1.0-1.7% – Improves oxidation resistance by forming a protective
oxide layer. Other Elements: Small amounts of silicon (Si), manganese (Mn), and copper (Cu)
may also be present. Grade | UNS | Density | Tensile Strength (MPa min) | Yield Strength (MPa min) | Reduction of Area min (%) | Elongation min (%) | Hardness (HRC) | INCONEL 601 | N06601 | 8.11 | 550MPa | 205MPa min | / | 40% min | / |
